Motorized conveyor cart with controller

Abstract

The invention provides a system for controlling the movement of a motorized cart on which a stud welder or grinder is mounted. The system comprises a speed control mechanism, distance control mechanism, and delay time control mechanism, each adjustable via potentiometer knobs. Directional control is managed by first and second three-way momentary switches and a three-way maintained switch for precise track movements. An LCD screen displays real-time settings, while an integrated power switch and wireless RF transmitter facilitate operation and communication with motor controllers. The custom software codebase ensures intuitive user adjustments. The method includes initializing the system, setting parameters, and controlling movement and operations via the interface. Additionally, an advanced ride cart system is described, featuring a lightweight composite body, touch-sensitive controls, safety features, and a high-capacity battery.

         20 . A method for operating a motorized cart configured to carry stud welding and/or grinding equipment along a workpiece, the method comprising:
 a. initializing a controller configured to control movement of the motorized cart along the workpiece;   b. receiving, via a user interface operatively connected to the controller, one or more operational parameters including at least a travel speed, a travel distance, and a stud count per row, wherein each row comprises a defined set of positions on the workpiece at which a predetermined number of stud welds are to be performed;   c. executing an iterative mode in which the controller:
 (i) detects each completed stud weld using one or more input signals indicative of a performed weld operation; and 
 (ii) advances the motorized cart from a current row to a next row along the workpiece after detecting that the predetermined number of stud welds have been performed in the current row; and 
   d. displaying, on a display screen, real-time information relating to the operation of the motorized cart, including data associated with travel and stud welding progress.   
     
     
         21 . The method of  claim 20 , wherein detecting a completed stud weld comprises receiving an input signal from a solenoid configured to detect when a stud is driven into a collet of the stud welder. 
     
     
         22 . The method of  claim 20 , wherein detecting a completed stud weld comprises receiving an input signal from a trigger of the stud welder indicating activation of the welding operation. 
     
     
         23 . The method of  claim 20 , wherein detecting a completed stud weld comprises sensing an electromagnetic spike produced during the welding operation. 
     
     
         24 . The method of  claim 20 , further comprising activating a misfire button to indicate that a weld attempt has failed or was incomplete, wherein activation of the misfire button prevents the controller from counting the weld attempt as a completed stud weld in the iterative mode. 
     
     
         25 . A control system for operating a motorized cart configured to carry stud welding and/or grinding equipment along a workpiece, the control system comprising:
 a. a controller configured to control movement of the motorized cart along the workpiece;   b. a user interface operatively connected to the controller and configured to allow adjustment of one or more operational parameters, including at least a travel speed, a travel distance, and a stud count per row, wherein each row comprises a defined set of positions on the workpiece at which a predetermined number of stud welds are to be performed;   c. an iterative mode executable by the controller, wherein the controller
 (i) detects each completed stud weld using one or more input signals indicative of a performed weld operation; and 
 (ii) advances the motorized cart from a current row to a next row along the workpiece after detecting that the predetermined number of stud welds have been performed in the current row; and, 
   d. a display configured to provide real-time information relating to the operation of the motorized cart, including data associated with travel and stud welding progress.   
     
     
         26 . The control system of  claim 25 , wherein the one or more input signals comprise a solenoid sensor configured to generate the input signal when a stud is driven into a collet of a welding gun. 
     
     
         27 . The apparatus of  claim 25 , wherein the one or more input signals comprise a welding gun trigger sensor configured to generate the input signal in response to activation of the welding operation. 
     
     
         28 . The apparatus of  claim 25 , wherein the one or more input signals comprise an electromagnetic sensor configured to detect an electromagnetic spike produced during the welding operation and to generate the input signal in response to the detected spike. 
     
     
         29 . A control system for operating a motorized cart configured to carry a stud grinder along a workpiece, the control system comprising:
 a. a controller configured to control movement of the motorized cart along the workpiece;   b. a user interface operatively connected to the controller and configured to allow adjustment of one or more operational parameters, including at least a travel speed, a travel distance, and a stud grinding count per row;   c. an iterative mode executable by the controller, wherein the controller:
 (i) advances the motorized cart along the workpiece to a next row based on a number of grinding operations completed at stud sites along a current row; and 
 (ii) detects completion of each grinding operation at a stud site using one or more input signals indicative of successful performance of the grinding operation; and 
   d. a display configured to provide real-time information relating to the operation of the motorized cart, including data associated with travel and grinding progress.   
     
     
         30 . The method of  claim 29 , wherein detecting that a grinding operation has been completed comprises receiving an input signal from a grinder trigger mechanism indicating activation or deactivation of the grinding operation.
